The Purdue Boilermakers are desperate to snap their four-game losing streak. They will hope to do that this evening when they host UCLA inside Mackey Arena in West Lafayette. Head coach Matt Painter, as well as guard Flecther Loyer, told reports on Thursday that it all starts with their aggressiveness on defense. Both say they have been lacking in that regard of late. The Boilers and the Bruins tipoff at 8-o-clock-eastern tonight.
